Similar to NSFW, another type of content that is difficult to define, but you know it when you see it, is the content that violates a common sense of decency. This classification will require a login, must be opted into, will not appear in search results or public listings, and will generate no revenue for Reddit.

Huffman said that a subreddit that actively encouraged the harm of other people would be banned, while those that were merely offensive—he gave the example of a subreddit promoting racist views—would remain on the site under the new classification.

Redditors predictably demanded more clarity on how exactly this offensive content would be defined. Huffman said he had tried a lot of names, and "nothing fit," but he wasn't particularly bothered. The "I know it when I see it" standard, Huffman said, comes with solid precedent: “It was good enough for the Supreme Court of the United States of America.”
